生活，我们学得太晚了，是在生活中，每天每时的组织。
Adult stem cells are also problematic, as they are difficult to identify, purify and grow, and simply may not exist for certain diseased tissues that need to be replaced.
成体干细胞也有问题，因为它们很难识别、纯化和生长，而且可能根本不存在某些需要替换的病变组织。
Through their work with fetal tissue, researchers hope to find ways to harness embryonic stem cells which have the ability to become any type of human cell and could provide new treatments for many illnesses.
通过对胎儿组织的研究，研究人员希望找到利用胚胎干细胞的方法。胚胎干细胞有能力成为任何类型的人类细胞，并能为许多疾病提供新的治疗方法。
When we talk about stem cells, we are actually talking about a complicated series of things, including adult stem cells which are largely cells devoted to replacing individual tissues like blood elements or liver or even the brain.
当我们谈论干细胞时，我们实际上是在谈论一系列复杂的事情，包括成体干细胞。成体干细胞在很大程度上是用来替代单个组织的细胞，比如血液成分、肝脏甚至大脑。
